i 'Application filed July v21,

Ations cut from old or used tire casings is attached about an ordinarytire casing for the purpose of protecting the same as well as extendingits wear or mileage, the inven-4 tion being particularly designed andadapted for utilizing old or lused tire casings.

More specifically speaking,l my invention relates to improved means vforindependently securing and adjusting such proteotive`casing sections,such means preferably comprising` a plurality of radially movable spacedtire carrying members or split rims adapted to detachably secure thesections of the protective casing and adjust the same through themediumv of improved relatively fixed and movable clamping membersadapted to be readily attached to and detached from any ordinary wheelfelly.

` The primary object of the invention is to provide a generally improvedstructure of the character mentioned which will be eX- ceedingly simplein construction, cheap of manufacture and eiiicient in use. v

A further and very important vobject of the invention is the provisionof .demount- .able clamp members which may` not onlybe attached to anyordinary wheel felly without -in any way marring or injuring the same,but the provision of improved radially Amovable tire engaging membershaving improved heel engaging hooks equally adapted to engage the-heelsof tire casings of either the straight side type or of theso-called clencher type. f

, With the above mentioned and other ends in view, the inventionconsists in the novel construction, arrangement and combination ofparts, hereinafter described, illustrated in some of its embodiments inthe accompanying drawings, and particularly pointed out in the appendedclaims.

Referring to the drawings, forming a part of this specification, yFigurel, is a frag- Specification of Letters Patent. 1331391115641 June '7,v1921.

The wheel l, rim 2,andfelly 8, may be of any suitable and convenientform, andvso likewise the casing 4, and inner tube 5.V In

`thepresent instance, the rim'2, and casing 4C,

:are of the clencher type, as shown in Figs. A1 and2, ofthe drawings,and of the straight -.side type, asv shownin Fig. 3, of the drawings.

The protective casingcomprises a plurality of labutting casing sections6. j The cas- ,lng sections 6, may be cut into suitable lengths from oldor V,used tires, but are preferably `of likey form andk dimensions andrelatively short in length, thereby forming 'j anumber of heatcontracting and expanding joints 6a, such sections and joints lesseningthe danger of great frictional heat andy heat and air expansion,resulting yin blow outs.

JThe joints 6a, preferably extend in a `direction slightly inclined fromradial klines drawn from the wheel center, as shown most t clearly inFig. l.

As 'a ymeansof securing and adjusting the casing ,sections 6, radiallymovable spaced tire engaging'members or hrims 7, are pro-y vided, saidmembers or rims 7 being mount ed atthe sides ofthe wheelfelly andterminating in casing engaging hook membersna,

the latter being preferably in the form of clencher members adapted toconform to and engage with the clencher portions of the casing sectionswhen the latter are orl the clencher type.vk

As a means, however, of more ett'ectually engaging the heel portions ofthe casing, and particularly as a means of engaging the heel portions ofa casing of the straight side type, as shown in llig. 3, ot thedrawings, the heel engaging members 7a, are preferably provided abouttheir inner periphery with a series of spaced heel penetrating teeth orprongs 7b, as shown most clearly in F ig. 6 or' the drawings.

As a means oic movably securing the tire securing members or split rims7, wheel telly engaging members are pro fided, said members, in thepresent instance, being in the specific form of relatively Xed tellyengaging clamp members S, provided with a telly receiving recess andterminating at their sides in guide members 8a.

As a means of forming a seat or guide portion for the clamping device orbolt and the relatively movable tire and tire rim engaging clampmembers,hereinafter referred to, the demountable or telly engaging clampmembers 8, are preferably provided with openings 8b, adapted to form aseat for a concave-convex shaped clamp thrust receiving ring SC. t willbe seen that the guide members Sa, at the sides of the wheel telly restagainst the inner sides of the tire casing engaging members or rims 7,and centralize and stabilize the latter in their various adjustments, ashereinafter referred to.

As a means of detachably connecting the tire section engaging members 7,to the wheel telly, and particularly as a means of adjusting the sameindependently of each other, the members or rims 7, are provided abouttheir inner periphery with extension members 7C, terminating in inwardlyextending hooks 7 d, the latter being adapted to be engaged byoppositely extending hooks 9a, formed at the sides of the rela-tivelymovable clamp members 9. The clamp mem bers 9, in the present instance,are in the specific form of clamp shackles and the movable clamps 9, areprovided with centrally located threaded openings adapted to receive andcontain clamping and adjusting bolts 10, the latter being adapted to beseated upon the thrust receiving ring 8, or' the relatively Afixed clampmembers and the adjusting devices or bolts l0, being adapted to besecured in adjusted position by means of lock nuts 10a.

As a means of preventing relative circumferential movement between thecasing engaging members 7, and the hooks 9, ot the relatively movableclamp or shackles, the hook receiving recesses 9b, ot the latter arepreferably closed at their ends by means of end walls or abutments 9,(see Fig. 4) the abutments 9C, being adapted to abut against the ends otthe hooks 7b, ci the radially movable members or rims 7. Y

By reason oli the construction above de-` scribed and illustrated in theaccompanying drawings, it will be obvious that the clamping devices orbolts l0, not only serve to attach the parts to or detach the parts fromthe wheel telly but also act to firmly draw the tire casing sectionengaging members or rims 7, toward the wheel center and the centrallylocated clamping devices l0, being located centrally, the pullingstrains and stresses are equalized on the two sides, and it will also beobvious that the guide members 8a, will'v stabilize the parts as againstlateral movement curing the varying exigencies or actual service.

From the foregoing description, taken in connection with thevaccompanying drawings, the operation and advantages of my inventionwill be readily understood.
